U.S. – Rep. Katherine Harris acknowledged Tuesday that investigators probing a bribery scandal have sought records from her Senate campaign, but she denied suggestions by a former top adviser that she is a target of the investigation.

Still, there were indications her campaign was increasingly involved in the investigation of former defense contractor Mitchell Wade, convicted of bribing a California congressman.

Since the beginning of April, campaign finance reports show, the Harris campaign has paid $35,806 to a high-powered Washington lawyer, Benjamin L. Ginsberg, who specializes in campaign finance law. Harris retained Ginsberg, of the firm Patton Boggs LLP, shortly after she was identified as having received illegal political contributions from Wade.

Former campaign consultant Ed Rollins, who recently was interviewed by Department of Justice investigators, said Tuesday that Harris is a subject of the investigation.

"There’s no question they’re focusing on her," he said.

Rollins said FBI agents and two lawyers from the Defense Investigative Service quizzed him on Harris’ interactions with Wade in a two-hour interview two weeks ago at the Justice Department’s Public Integrity Section. That section investigates allegations of corruption.

Wade’s company, MZM Inc., stood to benefit from an "earmark" spending provision Harris unsuccessfully sought to slip into military spending legislation last year.
